GRAlN -CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 722,108, dated March 3, 1903.

Application filed October 31, 1902. Serial No. 129,570. iNo model.:

To aZZ whom, it may concern.-

Be it known that I, JOSEPH H. A. HUOK, a citizen of the United States, residing at Salisbury, in the county of Ohariton and State of Missouri, have invented certain new and useful Improvements in Grain -Oar Doors, of which the following is a specification.

This invention relates to car-doors, and particularly to that class of grain-car doors made to fold one part upon the other when the door is open and such parts arranged to hang in alinement with each other when the door is closed.

The object of this invention is to provide a foldable swinging and slidable two-part graincar door of such novel and peculiar connection and arrangement relative to the interior of the car that waste or escape of grain, particularly during transportation, is entirely prevented.

A further object of the invention is to provide a foldable vertically-slidable two-part grain-door having hinges of such peculiar construction and arrangement that they constitute the door-hanger and permit the lower part of the door to be folded upon the upper part and in this position to be slid upwardly and swung inwardly to a position perpendicular to the side ofthe car.

A still further object of the invention is to provide a special clamping device carrying a series of bolts which are slidable with the clamp in a direction at right angles to the direction in which the door slides and which are capable of adjustment to vary their pressure on the door.

In the accompanying drawings, forming part of this application, Figure 1 is an interior perspective view of so much of a graincar as is necessary to illustrate my invention. Fig. 2 is a vertical section on the line a: 50, Fig. 3, showing the door raised or open and folded in dotted lines. Fig. 3 is an elevation showing the clamps out of contact with the door. Fig. 4 is a detail perspective view of one of the anchors and part of a clamp. Fig. 5 is a perspective view of one of the doorhanger rods.

The same numeral references denote the same parts throughout the several views of the drawings.

The side of the car has the usual doorway 1. One of the roof-rafters 2 is provided with a hook 3. Adjacent the door-jamlos 1 and secured thereto back of the inner car-casing 5 is one end of the door-hanger rods 6, and the other ends of said rods extend through the top car-beam 7 and are secured thereto by nuts 8. These rods are U-shaped, so as to form a lower arm 9, which rests on the top edge of the casing 5, and a like upper arm 10, the purpose and function of which will hereinafter be more fully described.

The door is composed of a lower part 11 and an upper part 12, the meeting edges of which are beveled and provided with abutment-shoulders 13, so as to form a close joint, such as will prevent escape of grain and which will exclude the beating in of rain or dripping from the car-roof. The door parts are foldably connected by hinges 14, the upper portion of which has a right-angle extension 15 over the top edge of the door and is provided with an elongation or slot 16, through which the rods 6 extend, so that the extensions 15 will rest upon the arms 9 when the door is in closed position, and when the door is elevated and folded the extension 15 rests upon the upper arms 10 in a position substantially parallel to the hanger-rods, so as to permit the folded door parts to lie flat together at right angles to the doorway close against the roof-rafter.

The car-casing 5 has a series of horizontal slots 17, through which extend slidable bolts 18,havingan anchor 19 and extending through clamps 20, where they are provided with nuts 21. The clamps have a shoulder 22, engaged by the side edges of the door, a flange 23 to overlap said door edges, and a series of projections 24, which act as a counter-bearing on the car-casing. The clamps are fixed over the ends of the door to permit the latter to slide without loosening the clamping-nuts, so that the door may be raised, but not folded, and when it is desired to fold the door the nuts are loosened and the clamps slid clear of the door ends to permit the door to he slid upon the hanger-rods and swung upwardly against the roof-rafter, where the door is held by the hook. It will be seen that the clamps are unmovable until the nuts thereof are loosened, that the nuts can only be operated from the interior of the car, that the door be ing hung from the interior of the car it cannot accidentally or otherwise be folded open, and that the hinges not only connect the door parts, but constitute the connection between the door and the door-hanger rods.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the foldable door, hanger-rods for the door, and the door-hinges having elongated projections over the door and Working on the rods, of the clamps to hold the door in slidable position Without folding it, anchors, and bolts connecting the anchors with the clamps to permit the latter to he slid away from the door to fold it.

2. The combination, with a car having inner longitudinal slots, the U-shaped hangerrods, a foldable door slidable vertically, and the door-hinges having an elongated projection over the top edge of the door and Working on the said rods, of the door-clamps having counter-bearing projections and slidable longitudinally over said slots, and the anchored bolts extending through the clamp, and provided with nuts, and slidable in the said slots.

3. The combination, with the hanger-rods, and the door parts having beveled meeting edges provided with shoulders, of the hinges connecting the door parts and having a rightangle, slotted extension over the top edge of the upper door part to engage said rods.

In witness whereof I hereunto set my hand in the presence of two witnesses.

JOSEPH H. A. HUOK.
